TECHNICAL FIELD

[0001] The present application belongs to the field of offshore ship design and construction, and particularly relates to a splicing and inserting type elastic support module. BACKGROUND

[0002] When the ship reaches the tail floating state, the support reaction force at the bow support point is very large, which is easy to cause structural instability and a large amount of structural repair work, resulting in a substantial increase in cost and affecting the delivery plan.

[0003] Generally, in order to achieve the requirement of rapidity, the hull plating of the bow region of the ship presents a V-shaped sharp line, and when the ship is launched, a center slipway needs to be arranged on the shipbuilding berth, and a wooden pad is arranged above the slide plate at the bow support point, and the effective contact area between the wooden pad and the outer bottom plate of the ship body is very small, so the center slipway is arranged with a bow support device which is consistent with the shape of the outer plating of the ship body, as shown in the figure. Figure 1 The bow support device in the existing design is a fixed bow support device, and a support device needs to be made according to the shape of the ship for each ship, which is discarded after the same type of ship is used. In addition, the bow support device is a relatively heavy structure, which needs to be transported to the shipbuilding berth by a crane, and is not easy to position. After launching, it needs to be recovered from the water, which is high in salvage and manufacturing cost, and has low utilization rate. SUMMARY

[0004] To solve the above problems, the present application provides a splicing and inserting type elastic support module, which aims to improve the utilization rate of the bow support module and reduce the construction cost of the actual ship, and the technical scheme adopted is:

[0005] The splicing and inserting type elastic support module has a rectangular iron frame, both ends and the top of the iron frame are open structures, the iron frame is composed of a frame main body and support bars fixed on the frame main body, a plurality of lateral support bars are vertically arranged on both sides of the frame main body, and a plurality of bottom support bars are transversely arranged at the bottom of the frame main body.

[0006] A combined wood module is fixed in the iron frame, a V-shaped groove is arranged in the center of the combined wood module, flat irons are pressed on both side edges of the top of the combined wood module, vertical bolts pass through the flat irons from top to bottom to fix the combined wood module, the combined wood module is composed of a plurality of wood blocks which are stacked from bottom to top, the lowermost layer is a common wood block, and the rest are spring wood blocks, the spring wood block is composed of an external square sleeve and a solid wood block inserted into the square sleeve, the square sleeve and the solid wood block are in sliding connection, and the side of the spring wood block close to the V-shaped groove is arranged at an inclination, and the inclination angle is A, 45°<A<70°.

[0008] Furthermore, in the aforementioned interlocking elastic support module, the height difference between the lowest and highest points of the groove is at least 500mm.

Detailed Implementation

[0026] The invention will be further described with reference to the accompanying drawings.

[0027] like Figure 2 As shown, a modular, elastic head support module includes a rectangular iron frame with open ends and top. Frame support strips are provided on both sides and bottom of the frame. The frame has the same height along its length. Multiple spring blocks are embedded in the frame and arranged sequentially along the height of the frame. The combined spring blocks have downward-recessed grooves in a V-shape. The bottoms of the V-shaped grooves are on the same horizontal line, and the height difference between the lowest and highest points of the grooves is at least 500 mm.

[0028] The top of the frame has two rows of flat irons that press down on the top of the wooden blocks. Vertical bolts pass through the flat irons and the wooden blocks one after another from the top of the wooden blocks downwards. The bottom of the frame has horizontal bolts on both sides. The horizontal bolts are close to the bottom of the wooden blocks and pass through the frame and the wooden blocks one after another from the outside of the wooden blocks to fix the wooden blocks inside the frame.

[0029] The iron frame is filled with modular wooden modules. Each module has a downward-recessed V-shaped groove in the center. Flat iron plates are pressed along the top edges of each module, and vertical bolts pass through these plates from top to bottom to secure the module. The modular wooden modules are composed of multiple layers of sub-blocks stacked from bottom to top, with the bottom layer being ordinary wooden blocks and the rest being spring-loaded wooden blocks. Figure 5 As shown, the spring block consists of an outer square sleeve 16 and a solid wooden block 17 inserted into the square sleeve. The square sleeve and the solid wooden block are slidably connected. The spring block is inclined on the side near the V-shaped groove at an angle of A, 45°. <A<70°。

[0030] The outer sleeve structure is a wooden structure with a certain thickness, which, together with the vertical bolts, plays a fixing role. The rubber plate 12 installed on the inclined side plays a protective role for the outer plate of the hull, which can greatly increase the contact area between the wooden module and the outer plate.

[0031] The bottom layer of wooden blocks is non-elastic, providing frictional resistance to the upper blocks. It has a groove in the middle for vertical support of the ship's bottom. The top layer of elastic wooden blocks is secured by the top and side flat irons of the iron frame. The bottom layer of elastic wooden blocks is secured by the front, back, and side flat irons of the iron frame. The top and bottom layers tightly connect the middle blocks, creating friction that restricts their displacement. The middle elastic wooden blocks are secured by the front, back, and side flat irons. All elastic wooden blocks have built-in springs that can compress independently according to applied pressure, but the maximum compression displacement is consistent. The initial state of the combined spring-loaded wooden module is 11, and the maximum compression displacement is 13.

[0032] Before constructing the combined spring-loaded wooden modules, an iron frame is made using angle steel and flat iron. The length and width of the iron frame are the same as the length and width of the skateboard. The main body of the frame is made of angle steel, and the frame support bars are made of flat iron. The frame support bars are divided into side support bars and bottom support bars. The side support bars are located on both sides of the frame, and the bottom support bars are located at the bottom of the frame. The side support bars are set vertically along the height direction, and the bottom support bars are set horizontally along the width direction. After the iron frame is constructed, several pieces of wood are placed in the iron frame along the width direction of the iron frame. The wood pieces are then tightened and fixed in place using through bolts in the longitudinal, transverse, and vertical directions.

[0033] The combined spring wood module has a groove cut out in the middle of the wood to maximize the contact surface with the hull plate. From the cross-section, the height difference between the lowest and highest points of the groove is at least 500mm, which is used to better absorb and digest the bow support reaction force.

[0034] Rotating rings 15 and connecting hooks 8 are installed on the vertical flat iron plates on both sides of the rectangular iron frame. The connecting hooks 8 can rotate on the rotating rings 15 and then connect to the adjacent iron frame. Elastic buckles 14 are installed on the vertical flat iron plates on both sides of the frame at the rear, which can be connected to the adjacent iron frame.

[0035] The rectangular iron frame and spring-loaded wooden blocks can be used together or separately. The number of flexible bow modules can be selected and combined according to different ship types and sizes. The combined structure is lighter than existing structures (which are solid), highly compatible, and can be customized according to ship type and tonnage, offering greater personalization. It also eliminates the need for relocation and facilitates positioning.

[0036] For ships with a relatively slender bow structure, a three-slipway launch configuration is typically used. High blocks are needed on the side slipways to increase the contact area, which is wasteful. This patent allows for the use of only a central slipway, reducing the three slipways in the bow area to one, saving costs and simplifying the manufacturing process.

[0037] For vessels with a slender, pointed bow shape, the traditional two-slipway system cannot accommodate the structural weight of the bow section. Therefore, a central slipway must be added between the original two slipways. Wooden modules are placed in the bow support area of ​​this central slipway. Figure 9 As shown in the diagram, a new temporary slipway has been added to the slipway center. Figure 9 It also specifies the strong zone of the slipway, and the bow support reaction zone of the vessel launched from the slipway must fall within this strong zone. Figure 9 It is a side view of the ship at its construction location on the slipway. Figure 10 This is a schematic diagram of stern buoyancy during ship launch. Before launch, a suitable tide height is selected through calculation. When the stern of the ship enters the water to a certain depth, the stern begins to float. The bow support, which enters the strong zone, is then subjected to force. The wooden module located on the central slide can effectively bear the bow support reaction force generated by stern buoyancy.
